First up, can lights. Yeah, they cast a beautiful glow over high-traffic exterior areas, but they're also an excellent source of security. The directional-style illumination can take the danger from a dark wall, then make it safe while also adding beautiful, cascading light.
While I often strongly discourage ceiling fans in spaces, I can't argue with using them in outdoor living rooms, especially being from Florida. The trick to using them without sacrificing aesthetics is to stay away from using ones with integrated lights. Instead, supplement with can lights in other areas of the ceiling.
Pendants: the best way to bring the look and feel of the indoors outside. While heavy wrought-iron fixtures like these help ground a space, they also require some upkeep in regards to frame and glass cleaning. My trick for maintaining outdoor fixtures is to (a) use the brush and extender attachments on a shop vac to rid them of dust, and (b) add an extender pole to a Squeegee to reach and clean the glass. Trust me, you'll find it worthwhile the next time you entertain friends without a dead bug falling from the light fixture above. Ha!
No electricity? No problem! Enter the world of the candelabra. Nothing says intimacy like a meal shared by candlelight; however, wax dripping from tapered candles above down onto your salad can totally kill the romance. Ensure that doesn't happen by investing in candle wax drip catchers such as these bobeches.
While chandeliers grouped together can be odd inside of the house, they work wonders in a vaulted ceiling outdoor space.
